PurposeTo评估代谢减少在同侧丘脑（TH）和/或对侧小脑（CE）根据肿瘤定位和皮质代谢肿瘤周围的患者与脑肿瘤FDG uptake.MethodsThis study investigated 48例连续孤立性大脑半球实质性脑肿瘤谁接受PET/CT和MRI。将患者分为4组（A：同侧TH和对侧CE的摄取减少，B：仅同侧TH的摄取减少，C：仅对侧CE的摄取减少，D：同侧TH或对侧CE的摄取无减少）。结果48例患者中，A组24例（50%），B组B 10例（21%），C组0例，D组14例（29%）。两组之间在肿瘤定位方面未观察到显著趋势。然而，在A组22例患者、B组7例患者和D组1例患者中观察到肿瘤周围皮质代谢降低。B组患者从肿瘤周围到同侧TH的代谢均降低。结论单发脑肿瘤患者同侧TH和对侧CE的FDG摄取减少通常同时发生。
PurposeTo evaluate reduced metabolism in the ipsilateral thalamus (TH) and/or contralateral cerebellum (CE) according to tumor localization and cortical metabolism around the tumor in patients with brain tumors based on FDG uptake.MethodsThis study investigated 48 consecutive patients with solitary cerebral hemisphere parenchymal brain tumors who underwent PET/CT and MRI. Patients were divided into 4 groups (A: reduced uptake in ipsilateral TH and contralateral CE, B: reduced uptake in ipsilateral TH only, C: reduced uptake in contralateral CE only, and D: no reduced uptake in ipsilateral TH or contralateral CE). FDG uptake and MRI findings were compared among these groups.ResultsOf 48 patients, group A included 24 (50%), group B included 10 (21%), group C included 0, and group D included 14 (29%). No significant tendencies were observed between the groups regarding tumor localization. However, reduced cortical metabolism around the tumor was observed in 22 patients in group A, 7 patients in group B, and 1 patient in group D. All patients in group B showed reduced metabolism from around the tumor up to the ipsilateral TH.ConclusionReduced FDG uptake in ipsilateral TH and contralateral CE usually occur simultaneously in patients with solitary brain tumors.
